Kohler Undertone double-basin sinks give you the option of rounded or squared basins to suit your individual preferences. This high/low undercounter kitchen sink with left basin depth of 5-1/2" and right basin depth of 9-1/2" is constructed of durable, stain- and corrosion-resistant 18-gauge stainless steel, and features SilentShield Plus, which sharply decreases the noise from dishes, running water and disposals.
